Great Sinkholes Documentary – Buried Alive

By Robert Armstead

In a recent PBS sinkholes documentary produced for the NOVA series, Sinkholes – Buried Alive, viewers learn about the geology that sets the stage for sinkholes across the globe, including karsts, limestone, gypsum, rock layers, salt domes and sandy soil.

The documentary also covers the warning signs for sinkholes and some of the experiments that geologists are conducting to understand how fast a sinkhole can occur, as well as the devastating effects of a massive storm dumping water onto the earth’s surface after water has been pulled from an aquifer for irrigation.

Most important, viewers learn about the different technologies and applications to detect and protect people and property from emerging sinkholes, including ground penetrating radar (GPR), soil testing, and different methods of soil stabilization.
